Application of antifreeze electric heating system on polar transport vessel
The electric heating system can not only heat electrical equipment, but also non-electrical equipment, which is a relatively bright and reliable application method. Therefore, the use of an electric heating system to protect equipment from freezing is a common method of protection against heating on polar ships.

When the vessel is sailing in the harsh conditions of the polar seas, the equipment on the open deck is subjected to huge tests. The materials of this equipment cannot be lower than the temperature and cold, but the normal use of the equipment must be guaranteed in this low temperature and cold environment.
Electric heating system can not only heat electrical equipment, but also non-electrical equipment, which is a relatively bright and reliable application method. Therefore, the use of an electric heating system to protect equipment from freezing is a common method of protection against heating on polar ships.
The entire electric heating system includes the following parts, a switchboard, an electric heating connection box, a heating cable and a temperature sensor. This article focuses on electric heating junction boxes and electric heating cables.
Electric Heating Distribution Box
As a connecting element between the power cable and the electric heating system in the electric heating system, the electric heating connecting box is connected to one end to the power cable, and the other end to the electric heating cable. Be installed outdoors and as close as possible to the equipment that needs to be heated. Requirement 50 ℃, protection class not less than IP56.
Our electric heating junction boxes are fully consistent with the low temperature conditions of the polar region, and the protection level of our electric heating junction boxes is IP66.
Electric heating cable
Electric heating cables suitable for polar transport vessels, usually we recommend self-regulating medium temperature electric heating cables and self-regulating high temperature electric heating cables. Parameters of two self-regulating heating cables:

Electrical heating installation precautions
Electric heating cable is a heating method that uses insulation resistance or resistance heating wire to create a temperature after power supply. It can automatically adjust the output temperature and reasonably maintain the process temperature requirements to keep warm, raise the temperature and protect the heating equipment from freezing. The insulation and antifreeze effect of the container is very good.
Which electric heating should be chosen for the main pipeline transport of heavy oil
Transport of heavy oil through the pipeline over long distances and long-term retention in the pipeline will result in a drop in temperature due to heat dissipation and increased viscosity, which will cause the pipeline to be blocked by freezing or condensation-related accidents. Electric heating is widely used as effective insulation of pipelines and anti-freeze protection.
Which electric heating cable should be considered for a 4 km pipeline
According to the statistics of the Hydrometeorological Center, the average daily minimum temperature at the location of the CNPC tank farm is 5 ° C, and the average daily maximum temperature is 14 ° C. Since the freezing point of the PX is about 15 °C, the supply pipeline needs heat preservation and heating. The oil depot has been in operation for many years without a stable source of steam, therefore, this project is considering the use of electric heating technology.
Application of outdoor electric heating cable in oil main pipelines with high paraffin content
Long-distance crude oil pipelines with a high paraffin content with freezing temperatures above 50 °C. According to the requirements of the production plan of the plant, the volume of oil transportation through the pipeline is 150 thousand rubles. Tons per year, maximum-200 thousand. Tons per year.. According to the thermodynamic analysis of the pipeline, the initial supply temperature of the pipeline is 80 ° C (TN), and the temperature of the end entering the tank is 60 ° C (Tu). Since the transportation temperature needs to be adjusted according to the time of year, it sometimes needs to be transported by heat.
What heating product to choose for main infusion pipelines
In petrochemical engineering, trunk infusion pipelines are the lifeblood of the factories. The temperature in the northern region is too low in winter and the pipeline needs to be insulated to compensate for the heat loss due to the low temperature in winter to ensure the normal operation of the pipeline.
The role of leather tracer cables in the insulation of asphalt main pipelines
The toughness of the asphalt is greatly affected by the temperature. When the temperature decreases, the toughness of the asphalt increases, and the drop in resistance of the asphalt during pipeline transportation increases; when the temperature falls below the freezing point, the asphalt solidifies, causing the pipeline to clog and the conveyor belt to come to trouble. Therefore, electric heating and heat preservation during the transportation of asphalt are very important.
